9011E, 9012E, 9000E and opening 9011H, 9012H, 9000H.Owing to having described the structure of vertical prism sheets 9011 and horizon prism sheet 9012 in the above, therefore, the descriptions thereof are omitted.

Vertical prism sheets 9011 and horizon prism sheet 9012 can be corresponding with the 3rd optical sheet.In embodiments of the present invention, vertical prism sheets 9011 and horizon prism sheet 9012 can be generically and collectively referred to as prismatic lens 9010.

As shown in Figure 17, the opening 9011H of

prismatic lens

9010 and 9012H can be overlapping with the opening 9000H of reflective polarizer 9000.

In this case, as shown in Figure 18, the projection 9020P of diffusing panel 9020 can pass the opening 9011H of prismatic lens 9010 and the opening 9000H of 9012H and reflective polarizer 9000.

As shown in Figure 18, consider the extension and the opening that when sheet is very thin, easily form sheet, the thickness Z 10 of diffusing panel 9020 can be greater than the thickness Z 12 of the thickness Z 11 of reflective polarizer 9000, vertical prism sheets 9011 and the thickness Z 13 of horizon prism sheet 9012.More specifically, the thickness Z 10 of the main part 9020B of diffusing panel 9020 can be greater than the thickness Z 11 of the main part 9000B of reflective polarizer 9000, the thickness Z 13 of the thickness Z 12 of the main part 9011B of vertical prism sheets 9011 and the main part 9012B of horizon prism sheet 9012.

As shown in Figure 19, when opening 9000H, the 9011H of reflective polarizer 9000, vertical prism sheets 9011 and

horizon prism sheet

9012 and 9012H overlap each other, thickness due to

extension

9000E, 9011E and 9012E, therefore the width P13 of the reflective polarizer 9000 on first direction DRH can be greater than the width P12 of the vertical prism sheets 9011 on first direction DRH, and the width P12 of the vertical prism sheets on first direction DRH 9011 can be greater than the width P11 of the horizon prism sheet 9012 on first direction DRH.

More specifically, the width P13 of the main part 9000B of the reflective polarizer 9000 on first direction DRH can be greater than the width P12 of the main part 9011B of the vertical prism sheets 9011 on first direction DRH, and the width P12 of the main part 9011B of the vertical prism sheets on first direction DRH 9011 can be greater than the width P11 of the main part 9012B of the horizon prism sheet 9012 on first direction DRH.

The size of the opening of optical sheet can be based on a plurality of optical sheets stacking order and change.For example, when the 3rd optical sheet with opening is at bossed the second optical sheet of tool with while having between the first optical sheet of opening, the size of the opening of the first optical sheet can be equal to or greater than the size of the opening of the 3rd optical sheet.

For example, as Figure 20 (A), (B) with (C), the big or small Z40 of the opening 9000H of reflective polarizer 9000 can be greater than the big or small Z30 of the opening 9011H of vertical prism sheets 9011, and the big or small Z30 of the opening 9011H of vertical prism sheets 9011 can be greater than the big or small Z20 of the opening 9012H of horizon prism sheet 9012.

In this case, the projection 9020P of diffusing panel 9020 can sequentially pass the opening 9000H of the opening 9012H of horizon prism sheet 9012, the opening 9011H of vertical prism sheets 9011 and reflective polarizer 9000.

Between the main part of at least one optical sheet and extension, can form at least one hole.More specifically, can form at the boundary of at least one main part and at least one extension at least one hole, and main part and extension can be distinguished from each other by the forming section of bent hole.

For example, as shown in Figure 21 (A), reflective polarizer 9000 can be included in the upper extension 9000E extending from main part 9000B of first direction DRH, and opening 9000H can be formed in the 9000E of extension.

Next, as shown in Figure 21 (B), can form at the boundary of main part 9000B and extension 9000E a plurality of hole 9000HP.

Next, as shown in Figure 21 (C), the border of main part 9000B and extension 9000E can be crooked, and extension 9000E is extended from main part 9000B on second direction DRV.

As above, at least one the hole 9000HP between main part 9000B and extension 9000E can help extension 9000E crooked.

Between the main part of at least one optical sheet and extension, can form auxiliary extension.More specifically, auxiliary extension can be formed between at least one hole and main part of the boundary that is formed at main part and extension.

For example, as shown in Figure 22 (A), reflective polarizer 9000 can be included in the upper extension 9000E extending from main part 9000B of first direction DRH, and opening 9000H can be formed in the 9000E of extension.

Next, a plurality of hole 9000HP can be formed in the 9000E of extension on first direction DRH the position with main part 9000B predetermined distance apart Z50.

Next, as shown in Figure 22 (B), when using the crooked extension 9000E of a plurality of hole 9000HP, can between main part 9000B and extension 9000E, form auxiliary extension 9000AE.In this case, main part 9000B and extension 9000E can be on first direction DRH preset distance Z50 separated from one another.

The width of auxiliary extension can be based on a plurality of optical sheets stacking order and change.For example, when the 3rd optical sheet with opening is at bossed the second optical sheet of tool and while having between the first optical sheet of opening, the width of the auxiliary extension of the first optical sheet can be greater than the width of the auxiliary extension of the 3rd optical sheet.

For example, as Figure 23 (A), (B) with (C), the width Z50 of the auxiliary extension 9000AE of reflective polarizer 9000 can be greater than the width Z51 of the auxiliary extension 9011AE of vertical prism sheets 9011, and the width Z51 of the auxiliary extension 9011AE of vertical prism sheets 9011 can be greater than the width of the auxiliary extension of horizon prism sheet 9012.In embodiments of the present invention, the auxiliary extension of horizon prism sheet 9012 can be omitted.

In addition, as Figure 23 (A), (B) with (C), distance QR3 between the end of the extension 9000E of hole 9000HP and reflective polarizer 9000 can be greater than the distance QR2 between the end of extension 9011E of hole 9011HP and vertical prism sheets 9011, and this can be greater than the distance QR1 between the end of extension 9012E of hole 9012HP and horizon prism sheet 9012 apart from QR2.

In this case, as shown in Figure 24, the width P20 of the width P20 of the reflective polarizer 9000 on first direction DRH, the width P20 of vertical prism sheets 9011 and horizon prism sheet 9012 can be almost mutually the same.

More specifically, the width P20 of the main part 9000B of the reflective polarizer 9000 on first direction DRH is, the width P20 of the width P20 of the main part 9011B of vertical prism sheets 9011 and the main part 9012B of horizon prism sheet 9012 can be almost mutually the same.

As shown in Figure 26, the second diffusing panel 9022 can have projection 9022P, and the first diffusing panel 9021 can not have projection.

In this case, the projection 9022P of the second diffusing panel 9022 can be corresponding with the opening 9011H of prismatic lens 9010 and the opening 9000H of 9012H and reflective polarizers 9000.

In addition, the first diffusing panel 9021 can be placed on the second diffusing panel 9022 simply.

In this case, optical sheet portion can have the structure shown in Figure 27.The thickness Z 14 of bossed the first diffusing panel 9021 of tool can not be greater than the thickness Z 10 of second diffusing panel 9022 with projection 9022P, to be easy to carry out projection formation processing.

As shown in Figure 27, the extension 9000E of reflective polarizer 9000 is, the end of at least one in the extension 9012E of the extension 9011E of vertical prism sheets 9011 and horizon prism sheet 9012 can be positioned at the side of the first diffusing panel 9021.In this case, can prevent the disengaging of the first diffusing panel 9021.
